Portfolio Management Flashcards
What is the portfolio perspective to investing?
The portfolio perspective refers to evaluating individual investments by their contribution to the risk and return of an investor’s portfolio
What are the benefits of diversification?
Diversification allows an investor to reduce portfolio risk without necessarily reducing the portfolio’s expected return.
In what circumstances would diversifying not be beneficial?
If the correlation of all the stocks in the portfolio = +1
What were Markowitz’s conclusions about diversification from his 1950 studies?
Unless the returns of the risky assets are perfectly positively correlated, risk is reduced by diversifying across assets
What is the formula for the diversification ratio?
( Diversification\ ratio = \frac{Standard\ deviation\ of\ equally\ weighted\ portfolio}{Standard\ deviation\ of\ a\ random\ security} )
What is the impact on diversified portfolios during times of financial crisis?
During periods of financial crisis, correlations tend to increase, which reduces the benefits of diversification. Diversification tends to work best when markets are operating normally
What are the three steps in the portfolio management process?
- Planning
- Execution
- Feedback
Which investor has a high risk tolerance, long term investment horizon, low liquidity needs and varying income needs depending on age?
DB pension schemes
Which investor has a low risk tolerance, a short investment horizon and high liquidity needs?
A bank
Which investor has a longer time horizon, DB pension schemes or life insurance companies?
Life insurance companies
A retirement plan in which the firm contributes a sum each period to the employee’s retirement account. Investment decisions and risk sit with the employee, the firm assumes none of the risk. What type of pension scheme is this describing?
A defined contribution pension plan
A firm promises to make periodic payments to employees after retirement. The employer assumes the investment risk. What type of pension scheme is this describing?
A defined benefit pension scheme
Who holds the risk in a defined contribution plan?
The employee holds the risk as the investment risk sits with them
Who holds the risk in a defined benefit plan?
The contributing firm holds the risk as they need to meet a set obligation upon the employees retirement
Who needs to fund the shortfall if investment performance along cannot fund a defined benefit pension?
The employer
Firms that manage investments for clients, are better known as…?
Asset management firms
What is the difference between a full service and a specialist asset manager?
Full-service asset managers are those that offer a variety of investment styles and asset classes
Specialist asset managers may focus on a particular investment style or a particular asset class
A holding company that includes a number of different specialist asset managers, is also known as a…?
Multi-boutique asset management firm
What is the difference between active and passive management?
Active management attempts to outperform a chosen benchmark through manager skill, for example by using fundamental or technical analysis
Passive management attempts to replicate the performance of a chosen benchmark index.
How much of total global AUM is passive?
20% of global AUM
Why has passive management become more popular in recent times?
Passive managers charge investors lower fees, and in part to questions about whether active managers are actually able to add value over time on a risk-adjusted basis
What securities do traditional asset managers invest in?
Equities and fixed-income securities
What securities do alternative asset managers invest in?
Private equity, hedge funds, real estate, or commodities
A portfolio that is owned by a single investor and managed according to that investor’s needs and preferences is called a…?
Separately managed account
What metric do we use to measure the value of the assets in a mutual fund?
NAV
What is an open-end fund?
The management company will sell shared directly to you. They will take your money, add it to the portfolio, and create more new shares
What is a closed-end fund?
When a closed-end fund starts, the company raises a set amount of money and issues a specific number of shares. No new shares are created after that point
What is the formula for the holding period return?
( HPR = \frac{P_1 + D_0 - P_0}{P_0} )
What is the formula for the arithmetic mean return?
( Arithmetic\ mean\ return = \frac{R_1 + R_2 +…+ R_n}{n} )
What is the geometric mean return?
( Geometric\ mean\ return = \sqrt[n]{(1+R_1)(1+R_2)…(1+R_n)}-1 )
What is the difference between gross, net and real return?
Gross return refers to the total return on a security portfolio before deducting fees
Net return refers to the return after these fees have been deducted
Real return is nominal return adjusted for inflation
What is leveraged return?
Leveraged return The gain or loss on the investment as a percentage of an investor’s cash investment.
Which asset class has historically led to the greatest returns and standard deviation
Small cap stocks
Explain the difference between a risk-averse, risk-seeking and a risk-neutral investor?
A risk-averse investor is simply one that dislikes risk
A risk-seeking investor actually prefers more risk to less and, given equal expected returns, will choose the more risky investment
A risk-neutral investor has no preference regarding risk and would be indifferent between two such investments
What graph represents the investor’s preferences in terms of risk and return?
Utility function
How do indifference curves behave for risk averse investors?
Indifference curves slope upward for risk-averse investors because they will only take on more risk (standard deviation of returns) if they are compensated with greater expected returns
What is the capital allocation line?
Possible portfolio risk and return combinations given the risk-free rate and the risk and return of a portfolio of risky assets.
What is fintech?
Fintech: developments in technology that can be applied to the financial services industry
Extremely large data sets that may be analysed computationally to reveal patterns, trends, and associations, especially relating to human behaviour and interactions, are also known as…?
Big data
What are the 4 characteristics of big data?
Volume, variety, velocity, veracity
What is the difference between structured and unstructured data?
Structured data is highly-organized and formatted in a way so it’s easily searchable in relational databases. Unstructured data has no pre-defined format or organization, making it much more difficult to collect, process, and analyze
Programmes to simulate human cognition, are called…?
Artificial Intelligence
What are neural networks?
Neural networks are an example of artificial intelligence in that they are programmed to process information in a way similar to the human brain
Systems that learn and improve from experience without being explicitly programmed are called…?
Machine learning
What is the difference between supervised and unsupervised learning?
supervised learning: the input and output data are labelled, the machine learns to model the outputs from the inputs, and then the machine is given new data on which to use the model
unsupervised learning: the input data are not labelled and the machine learns to describe the structure of the data
A technique that uses layers of neural networks to identify patterns, beginning with simple patterns and advancing to more complex ones, is called?
Deep learning
What is the difference between overfitting and underfitting?
Overfitting occurs when the machine learns the input and output data too exactly, treats noise as true parameters, and identifies spurious patterns and relationships.
Underfitting occurs when the machine fails to identify actual patterns and relationships, treating true parameters as noise.
